Package org.openl.rules.table

Class SimpleLogicalTable

java.lang.Object

org.openl.rules.table.ALogicalTable

org.openl.rules.table.SimpleLogicalTable

All Implemented Interfaces:

ILogicalTable, ITable<ILogicalTable>

public class SimpleLogicalTable
extends ALogicalTable

Adapts IGridTable, that doesn`t contain merged cells in the top row and left column to ILogicalTable interface.
Be careful, as this implementation doesn`t provide that following operations
ITable.getColumn(int)
ITable.getColumns(int)
ITable.getColumns(int, int)
ITable.getRow(int)
ITable.getRows(int)
ITable.getRows(int, int)
ITable.getSubtable(int, int, int, int)
will return right ILogicalTable. That is because all of them are based on getSubtable(int, int, int, int) method implementation.

Constructor Detail

SimpleLogicalTable

public SimpleLogicalTable(IGridTable table)

Method Detail

getWidth

public int getWidth()

Returns:

width of the table

getHeight

public int getHeight()

Returns:

height of the table

findColumnStart

public int findColumnStart(int gridOffset)

Description copied from interface: ILogicalTable

Calculates # of the column starting exactly at gridOffset. Throws TableException if gridOffset does not match any column's start.

Returns:

findRowStart

public int findRowStart(int gridOffset)

Description copied from interface: ILogicalTable

Calculates # of the row starting exactly at gridOffset. Throws TableException if gridOffset does not match any row's start.

Returns:

getColumnWidth

public int getColumnWidth(int column)

Parameters:

column - index of the column

Returns:

width of the column by its index.

getRowHeight

public int getRowHeight(int row)

Parameters:

row - index of the row

Returns:

height of the row by its index.

getSubtable

public ILogicalTable getSubtable(int column,
                                 int row,
                                 int width,
                                 int height)

This method consider that this table doesn`t have merged regions inside itself. In general it is not true. Current Openl parsing implementation, correctly handles such cases. If you need the trully ILogicalTable, with correctly calculated logical columns and rows, you may get the source table, by calling ILogicalTable.getSource() extract the region you need by calling ITable.getSubtable(int, int, int, int) and create ILogicalTable by calling LogicalTableHelper.logicalTable(IGridTable). This is optimised implementation because of time overhead when checking for each table is it really logical or not.
For test see SimpleLogicalTableTest.

Parameters:

column - from which we want to take the subtable, including this.

row - from which we want to take the subtable, including this.

width - of the needed table.

height - of the needed table.

Returns:

SimpleLogicalTable

getCell

public ICell getCell(int column,
                     int row)

Returns:

cell form the given column and row.
